A cutting nozzle is a device that is attached to a gas torch and used in cutting applications. It directs a high-pressure stream of gas, such as oxygen or propane, onto a metal surface to heat and melt the metal. The melted metal is then blown away by the gas stream to create a cut.
A cutting nozzle can be used with various gases, including oxygen, propane, acetylene, natural gas, and hydrogen. The type of gas used depends on the application and the type of metal being cut.
